12 turns #12 spaced .4 in. center to center apart w pickup loop 2 in.
from main loop. Will not overload my SDR. Tunes approx. 380 kHz to 2.1
MHz - top freq. depending on how much coax you feed it with. I used #
12 because I already had 2000 ft. Cost about 15 bucks for wood and
capacitor.

If you buy an amplified loop make sure it has a gain adjustment or it
will probably overload the radio.

Pretty sure Angelfire went bye-bye some time ago. I used to have a website
there back in the day, but they closed all their sites, IIRC.

It looks like its angelfire.lycos.com now but the web site link
still checks out here as is.

The expensive pixel loop is "shielded", don't forget. You are going to
have to shield the turns and stop local electrical field noise pickup,
hence, the length of copper tubing I mentioned ... aluminum could work ...

If you want a VERY close to exact copy ... somehow, I think most have
missed that.
